    Vitamin B2 enables regulation of fasting glucose availability

    Peter M Masschelin, Pradip Saha ... Sean M Hartig
    The dietary vitamin riboflavin provides the chemical backbone to generate essential substrates that support liver glucose metabolism during low-nutrient conditions.

    The Opto-inflammasome in zebrafish as a tool to study cell and tissue responses to speck formation and cell death

    Eva Hasel de Carvalho, Shivani S Dharmadhikari ... Maria Leptin
    Manipulating cell death in situ with the temporal and spatial precision of optogenetic tools opens up new avenues for studying inflammation, death and related phenomena, revealing, for example, that epithelial cell death cannot be classified into strictly distinct categories.

    CCR4 and CCR7 differentially regulate thymocyte localization with distinct outcomes for central tolerance

    Yu Li, Pablo Guaman Tipan ... Lauren IR Ehrlich
    Two-photon microscopy, combined with chemotaxis assays, synchronized thymocyte selection studies, and flow cytometry analyses, reveal that CCR4 and CCR7 promote medullary entry and central tolerance of immature and mature post-positive selection thymocyte subsets, respectively, with distinct outcomes for central tolerance.

    The ER folding sensor UGGT1 acts on TAPBPR-chaperoned peptide-free MHC I

    Lina Sagert, Christian Winter ... Robert Tampé
    The endoplasmic reticulum (ER) folding sensor UGGT1 essentially cooperates with the peptide editor TAPBPR to provide quality control of MHC I molecules in the antigen presentation pathway.

    α1-Adrenergic receptor–PKC–Pyk2–Src signaling boosts L-type Ca2+ channel CaV1.2 activity and long-term potentiation in rodents

    Kwun Nok Mimi Man, Peter Bartels ... Johannes W Hell
    The α1-adrenergic receptor augments the activity of the L-type Ca2+ channel CaV1.2 through PKC and the tyrosine kinases Pyk2 and Src and thereby synaptic plasticity.

    A simple mechanism for integration of quorum sensing and cAMP signalling in Vibrio cholerae

    Lucas M Walker, James RJ Haycocks ... David C Grainger
    Overlapping DNA-binding specificity allows global transcription factors to cooperatively bind the same DNA sites and integrate two signals in the control of gene expression.

    Remapping in a recurrent neural network model of navigation and context inference

    Isabel IC Low, Lisa M Giocomo, Alex H Williams
    Recurrent neural networks trained to navigate and infer latent states exhibit strikingly similar remapping patterns to those observed in navigational brain areas, inspiring new analyses of published data and suggesting a possible function for spontaneous remapping to support context-dependent navigation.

    Connectomics of the Octopus vulgaris vertical lobe provides insight into conserved and novel principles of a memory acquisition network

    Flavie Bidel, Yaron Meirovitch ... Binyamin Hochner
    Connectomics of the octopus 'fan-out fan-in’ learning network reveals that the intermediate layer uses approximately 22×106 excitatory interneurons, each can store a single sensory input, while approximately 400×103 integrating inhibitory interneurons adjust the network output level.

    The evolutionary mechanism of non-carbapenemase carbapenem-resistant phenotypes in Klebsiella spp

    Natalia C Rosas, Jonathan Wilksch ... Trevor Lithgow
    Genetic, phenotypic, and evolutionary analysis of a clinical isolate provides an explanation of the intricate genetic factors behind non-carbapenemase carbapenem resistance and sheds light on the evolutionary mechanisms that influence the molecular basis of antibiotic resistance.

    Defining function of wild-type and three patient-specific TP53 mutations in a zebrafish model of embryonal rhabdomyosarcoma

    Jiangfei Chen, Kunal Baxi ... Myron S Ignatius
    Zebrafish are an optimal model organism to study rare TP53 mutations whose functions are not readily understood.
